182 Mr. F. P. Pascoe on Additlutus fo 



collection of more than a thousand species of Ciu-culionidaj 

 only five or six species belong to the Erirhininae. In the table 

 I have followed Lacordaire's division into live "groupes;" but 

 it seems to me that two of these (" Cryptoplides " and " Sto- 

 reides") cannot be maintained satisfactorily, and should be 

 united to "Erirhinides vrais." Some of the genera might be 

 placed in either of them. 



" ErIRHINIDES A'EAIS." 



Pectus not canaliculate. 



Club of the antennee with closely united joints. 



Scrobes nearly terminal Dcsiantlut. 



Scrobes more or less distant from the mouth. 



Rostrum quadrangular Ncmestra. 



Rostrum rounded or cylindrical. 



Antennae inserted near the base of the rostrum . . Orichura. 

 Antennas inserted near the middle. 

 Femora not toothed. 



Scrobes connivent beneath Aiyphcnemis. 



Scrobes not connivent. 

 Anterior tibiae spurred. 



Anterior tibiae .«lightly flexuous Erirhinus. 



Anterior tibi;e falcate CEudchronui. 



Anterior tibise not spurred Xedijlcda. 



Femora toothed beneath , Ai/edra. 



Club of the antennae loosely jointed Kniopca. 



Pectus canaliculate -. Diethusa. 



•' IIydroxomidks." 

 Pectus caualiculate Bayutis *. 



" CnYI'TOt'LIDKS." 



Funicle G-jointed. 



Taisi 4-jointed Endalm. 



Tarsi 3-jointed . Misophrice, 



Funicle 7-jointed. 



Elytra Ciillous posteriorly liliuchiudcH. 



Elytra without callosities. 

 Tarsi 4-jointed.

" Stoeeides," 

 Funicle 7-jointed. 

 Pectus canaliculate, 



Ro.strum cylindrical Lyba-ha. 



Rostrum narrowing gradually to the apex Enide. 



Pectus not caualiculate. 



Second abdominal segment scarcely longer than the 



third Storetis. 



* I have three Australian species of this well-known northern genus. 



t This genus will be published in my " Contributions towards a 

 Knowleflge of the Curculionidae/' Part iv., in the Journal of the Linnean 

 Society. It i.« related to a new Malayan form.
